Abstract This document specifies a new Multimedia Internet KEYing (MIKEY) General Extension payload to transport the short-term key message (STKM) and long-term key message (LTKM) payloads as well as the management data LTKM reporting message and parental control message payloads defined in the Open Mobile Alliance's (OMA) Broadcast (BCAST) group's Service and Content protection specification.

Introduction The Multimedia Internet KEYing (MIKEY) protocol specification (RFC 3830 [RFC3830]) defines a General Extension payload to allow possible extensions to MIKEY without having to allocate a new payload type. The General Extension payload can be used in any MIKEY message and is part of the authenticated/signed data part. There is an 8-bit type field in that payload. The type code assignment is IANA-managed, and RFC 3830 requires IETF consensus for assignments from the public range of 0-240. The Open Mobile Alliance's (OMA) Broadcast (BCAST) group's Service and Content Protection specification [SPCP] specifies the use of a short-term key message (STKM), a long-term key message (LTKM), an LTKM reporting message, and a parental control message that carry attributes related to Service and Content protection. Note that any keys associated with the attributes, such as the Parental Control Pincode if present, are part of the MIKEY KEMAC payload. This document specifies the use of the General Extension payload of MIKEY to carry the messages mentioned above, as well as protection of the credentials using mechanisms supported by MIKEY with modifications in [RFC3830]. RFC 3830 [RFC3830], the MIKEY General Extension payload defined in RFC 4563 [RFC4563], and the 3rd Generation Partnership Project (3GPP)'s Multimedia Broadcast/ Multicast Service (MBMS) document [3GPP.33.246] specify the transport of MIKEY messages via unicast or broadcast; the OMA BCAST specifications use either for transport of MIKEY messages.

Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. OMA BCAST MIKEY General Extension: We refer to the General Extension type -- 5 -- as the OMA BCAST MIKEY General Extension. 3. MIKEY General Extension for OMA BCAST Usage The OMA BCAST Type (Type 5) formats the MIKEY General Extension payload as follows: 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+Show full document text
